last night i removed mate-screensaver to make sure that

wasn't the issue. it isn't as i had the same thing happen

this morning.

moving the mouse would seem to be the way to get the

screen to come back on, but that doesn't do anything.

i did find out a bit ago though that if i turn the volume

knob on the USB speaker it will bring the display back up

to where i can see again, but i'm not sure what else may be

going on here.

This sounds like a hardware issue to me. After checking the cables

as previously suggested, my next idea would be to try a different

cable, or a different monitor. (In any case, it would probably be

helpful to know how the monitor is attached to the computer -- VGA,

HDMI, Display Port?)

HDMI cable connection, not ever had a problem with one

of them before. i will check the connection.

That last bit about the speaker volume affecting the display is really

strange. I don't understand how those two devices are interacting.

one of the items on my top panel is a volume slider.

i'm suspecting some kind of power saving setting, but

i'm not sure where.

You can access the power options via the Screensaver menu.

On my Sid Mate I get a lock screen, even with that turned off.

Sid Mate is buggier than in the past.
